CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 644,780, dated March 6,1900.

Application filed August '7, 1899.

To tel]. whom, it may concern:

Be it known that I, URIAs SHAEFFER, a citizen of the United States,residing at Lancaster, in the county of Fairfield and State of Ohio,have invented a certain new and useful Improvement in Corn-Planters, ofwhich the following is a specification.

My invention relates to the improvement of hand corn-planters, and hasparticular relation to the improvement of that portion of the planterwhich is known as the seed cut-off.

The objects of myinvention are to provide an improved cut-off of thisclass which will be simple and inexpensive of construction and which atthe same time will be durable and effective when in use and to provideother improvements in details of construction and arrangement of parts,which will be more fully pointed out hereinafter. These objects Iaocomplish in the manner illustrated in the accompanying drawings, inwhich- Figure 1 is a view in perspective, showing the character of handcorn-planter to which my invention applies. Fig. 2 is an under side viewof the seed-cut-olfframe and cut-off therein. Fig. 3 is a detail view inperspectiveof a portion of one of the planter-legs, showing the seed.disk mounted upon a bracket-casting projecting from said legs at theusual point. Fig. 4 is a detail view in perspective of the cut-offframe-ri-n g, showing my improved cut-off therein. Fig. 5 is a detailview in perspective of'a portion of the cut-01f ring and cut-off, andFig. 6 is a detail view in perspective of the cut-off.

Similar numerals refer to similar parts throughout the several views.

land 2 respectively represent the usual jointedlyconnected legs of ahand. cornplanter, the leg 2 being provided with a projecting casting orbracket 3, on which is retatably mounted a desirable form of seed-disk4, the latter receiving its intermittent rotary motion through theengagement therewith of operating-arms 5, which are connected with theleg 1. The feed-disk 4 is provided in the usual manner with the desirednumber of eccentrically-arranged feed-openings 6, which are designed byrotation of said disk to register successively with a feed-opening inthe casting 3. This construction and operation,

Serial No.726,361. (No model.)

however, is clearly set forth in my former patent, No. 571,935, datedNovember 24, 1896.

7 represents the cylindrical hopper, which, asset forth in said formerpatent, is secured to the forward leg 2 and has its otherwiseopen lowerend provided with a cut-off frame ring 8, the latter being supportedimmediately above the feed-disk 4.

In constructing the frame-ring 8, which is substantially of a D shape, Icause the same to be intersected by a cross-arm or web 9, the

latter being formed on one side with an upwardly-projecting pocketportion 10, through the upper side of which is formed a small opening11. i

12 and 12 respectively represent oppositelylocated bearing notches orrecesses, which are formed, respectively, in the under side ofthering-frame or web 9 and the corresponding side of the inner portionof the ring 8.

14 represents my improved cut-off, which, as indicated in the drawings,is in the nature of .a metallic casting,theinnerend portion of whichturns upward and thence outward in the direction of the length of thecasting, the horizontal termination 15 thereof being recessed centrally,as indicated at .16, and provided on opposite sides of said recess withdownwardly-projecting lugs 17. At a point near the center of the lengthof the casting 14 Iprovide oppositely-located and laterallyprojectingtrunnions 18, which, as indicated in the drawings, are adapted to bearwithin the oppositely-located recesses 12 of the ring 8. The outer endportion of the cut-off 14 is provided with a downturned and inclinedshoulder or tooth 19. For reasons hereinafter set forth the under sideof the cut-off is so formed as to present no sharp angles, and theupwardly'projecting portion of said cut off is, as indicated at 20,preferably rounded or concaved on its inner face. In order to provide aspring-actuated connection of the seed cut-off with the ring 8, I employacoiled spiral spring 21, the upper and larger end. of which embracesthe projectinglugs 17 of the cut-off, While an extension of the wirewhich forms the spring passes upward through the spring,'from thetapering end of the latter through the slotted opening or recess 16 ofthe contact with the surface of the disk.

the ring-frame pocket, where it is looped, as indicated at 12, toprevent its return through said opening. In this manner the cut-off isactuated by a spring and its downturned tion 15 of the out off willcontact in case the latter is tipped an undesirable distance.

From the construction herein shown and described it will readily be seenthat a simple and inexpensive form of cut-off and supporting-ring isprovided, and that being formed of metal the same will be exceedinglydurable. It will also be observed that in the manner described thecoiled spring is made to serve both the purposes of hinging the out offto the ring-frame and of retaining the lip or shoulder portion 19 indesirable frictional Owing to the fact that the under side surface ofthe cut-off presents no sharp angles or corners it will be seen that thetendency toward the grain sticking orlodging thereon is obviated.

In case it is desired to remove the cut-off it is evident that the samemay be so manipulated as to admit of its withdrawal from beneath thespring and disconnection of the latter without the removal of saidspring.

I am aware that metallic cut-offs have been employed heretofore in otherclasses of cornplanters and that the same have been actuated by a coiledspring; but such construction differs from that herein set forth andclaimed.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. In a corn-planter, the combination with a planter-frame, a perforatedrotating disk mounted thereon, of a hopper mounted above said-disk, aring-frame in said hopper, a metallic cut-off fulcrumed in said frameand having an end recess 16 and a coiled {spring having an extension atone end which passes through said end recess and engages the ringframeand having its remaining end bearing on the inner end portion of saidcut-off and retaining the latter in place, substantially as and for thepurpose specified.

2. In a corn-planter cut-off, the combination with a frame-ring 8 havinga cross-arm or web provided with a pocket or depression, of a metalliccutoff fulcrumed in said ring and having a projecting portion adapted tobear in said ring-pocket, said cut-off being provided with a downturnedlip portion 19 and a coiled spring, the upper portion of which retainsthe cut-off in hinged connection with the ring and the extension of thelower end of which passes through said coil and engages said ringcross-arm, substantially as and for the purpose specified.
